Weldbrite utilises innovative Australian technology for the formulation of a high adhesion stainless steel pickling gel for pickling applications It is used to remove the black oxide marks or burn scale left during welding of stainless steel. This product conforms to the international standard, ASTM A380-17. The standard practice for cleaning, descaling & passivation of stainless steel parts, equipment & systems. After the use of Weldbrite, the weld area should have the same look as the rest of the steel being used. Weldbrite leaves a clean professionally finished stainless steel weld area, free from contamination.

Direction for use

1. Clean the weld area carefully using a stainless-steel brush.
2. Roll or shake the drum of Weldbrite if possible for 30 seconds prior
to opening the container to ensure a smooth consistency. 3. After welding ensure the area to be pickled has sufficient time to cool below 40⁰C.
4. Apply the Weldbrite gel to the area to be cleaned, using the brush provided or with an acid-resistant spray pump and applicator. DO NOT PICKLE IN DIRECT SUNLIGHT.
5. Application times may vary depending on ambient temperature, the grade of stainless, surface.
6. To clean, rinse the surface with clean potable water. The best results are obtained by the use of a high-pressure water jet or similar. Ensure the pickle residues are not left on the surface.
